ZFS extramodules; i.e.,
linuxXX-zfs, have been dropped from the repos. There have been recent difficulties building them and no one on the Manjaro Team uses ZFS.Please install
zfs-dkmsinstead. You will to need to manually remove the old 2.1.13 extramodule package(s) first to install the new 2.2.0 packages; i.e., withlinux61:sudo pacman -R linux61-zfs && sudo pacman -Syu zfs-dkms
Have you tried using r8168 driver instead of r8169 driver ?
